s claims. (on 2 168) (Grantee under the not of Msi-en s. 1883, as amenace` April so, 192s; 37o o. o.. 757) 'I'he invention' described herein may be manufactured and used by orfor the Government for governmental purposes, without the payment to me of any royalt1 thereon.

This invention relates to the manufacture of protective glovesv which are specially treated to several necessary substances and compounds and protect the wearer thereof from the vesicant effect of various chemicals such as mustard gas.

It is well known that modern warfare involves the use of various gases which have more or less injurious effectsy upon the skin of those coming in contact therewith.

Many protective devices have been developed the materials treated may be widely varied, the following description being by way of example only and without limiting the invention Itothe specific embodiments set forth.

Figure 1 is an elevation lof the glove and impermeable lining, with a portion of the fabric and lining broken away.

Figure 2 is an enlarged section o! the fabric partially separated from the coating.`

v Figure 3 is a similar section of; a'modied form.

for the protection of persons exposed tothese gases, either at the battlefront or in the factory producing the gases and filling the 'shells or 'grenades therewith.

Heretofore no practicable gloves have beenv available which ailordcomplete protection to the hands of the wearer and yet have sufilcient ilexibility as not to materially interfere with the normal use of the hands.

'The principal object of this invention therefore, is to provide` a protective glove which is impermeableto injurious gases.

Another object of this invention' is to provide a protective glove which is impermeable to injurious gases and which is sufficiently flexible to allow free use of the hand.

Another object of this invention is to provide a giove which fully protects the wearers hand against vvesicsnt gases while allowing free use of thailand, and which is durable inuse. f

Another object of this invention is to providea giove formed of an inner liner which is impermeable to vesicant gases such as mustard gas, and an outer waterproof giove capable of withstanding the normal wear to which the glove is subjected and protecting the inner liningfrom mechanical injury and moisture. I

A further object of this invention is to, provide s giove formed of an inner liner and an outer :love as above described and which is not cum-` bersome nor stiff in use. s nii-mer object of uns invention n to provide a protective inner liner for gloves composed of s relatively iight fabric treated to render the same impervious to vesicant gases. More speeillcallyV 'it is an object of this invention to provide a so sewed seams of these inner gloves are next ren.

linerl of this character treated with viscose' latex. so

cellophane, viscose compounds or similar protective materials.

These and other objects of this invention .will be apparent iromthe following description and appended cisims, it being understood that the se 'Figure dis a section showing a. seam of the lining, and the assembly with the outer glove.

One preferred embodiment oi this invention is as follows. A relatively light and flexible fabric I such as cotton fabric, balloon cloth, or the like, is treated with a compound 2 to render it impermeable .to mustard gaa or similar gases. The compound used for this purpose is a cellulose derivative. such as viscosal latex, Cellophane; or other viscose compounds. i Excellent results have been obtained by the use 'of viscose-rubber latex as a coating.

The coating mixture 2 may be applied to the fabric in any approved manner. As one ex` ample, 2-ounce cotton fabric I lightly coated -with rubber 4 on one side. to which a thin coatfabric with viscose'or viscose-rubber latex Plssticized with glycerine. without the initial iight coat of rubber and without the addition of glue. This preferred embodiment gives ample protection against vesicant gases and liquids and allows full freedomof the hand.

The coated fabric is then cut to the shape of a,` glove. and the seams carefully scwed. The

ded resistant to mustard gas or similar gases by covering them with rubberized tape l, es seen in Figure 4. A preferred method. however. is to' coat the seams. with rubber latex or cellulose nitrate or cellulose acetate composition, preferably by spraying'. l

The inner glove made as described is then inserted into an outer wear-resistant giove of any suitable type auch as cotton fabric glove I coated with a plasticized cellulose nitrate composition lor example, or a drying oil composition, or leather or canvas glove. Preferably the coated side of the liner is placed next to the inner side of the outer glove. Prior to assembly of the inner and outer gloves, however, both gloves are impregnated with gly'oerine to preserve lflexibility.

The inner liner is then securely fastened with- I in the outer glove by .stitching 9 along the top of the glove and also around the opening for the r hand.

Cil

present invention afford protection against penetration by liquid mustard for fteen hours. Furthermore, the durability of these gloves is such that they will ontlast several pairs of cellulose nitrate-rape seed oil coated gloves previously in use, and are more exible and comfortable.

Tests have demonstrated that gloves made in accordance with this invention wherein a vesicant chemical resistant inner liner is secured at spaced points within a wear and moisture resistant outer glove, afford excellent protection. This type of assembly results in a glove with a mustard gas resistance many times greater than the sum of the mustard resistance value of the constituent layers of the material, due to the main portion of the layers being unattached and slightly spaced from one another. 'I'he exibility of this glove is also greater than that obtained by the same layers joined together throughout. The multiple layer construction allows the utilization of many materials which otherwise have proved to be valueless where flexibility, gas resistance, and durability are essen tial requirements. A v It will be seen therefore that the present invention provides gloves which aord full protection against injurious gases for long periods of time, are extremely durable, and allow complete fiexibility of the hand.

While I have described the preferred embodiment of my invention, I- wish it to be understood that the invention is not limited to the precise ingredients and steps described herein by way of illustration, as it will be apparent that many changes in variations may be made without departing from the spirit of the invention or the scope of the appended claims.

' I claim:

, 1. A glove comprising an inner liner composed of fabric treated to render it impervious to vesicant gases, and an outer glove composed of wearresisting material, said liner and outer glove being secured together to maintain their assembly in assembled relation with their main surfacesv unattached.

3. A glove for protection against chemical warfare agents such as mustard gas comprising an inner liner composed of light flexible fabric coated with one of the compounds consisting of viscose, or other cellulose derivative, and an outer glove of wear-resisting material, said liner andv outer glove being attached only at widely spaced -extremities thereof to thereby provide an air space between the main portions.

4.` A glove for protection of the wearer against mustard gas and other vesicant chemical agents comprising an inner glove formed of light flexible cotton fabric having an impervious coating of viscose and rubber latex on the inner surface, and an outer glove of heavy waterproof wearresistant material, said inner and outer gloves being assembled and secured together at widely spaced portions, whereby an air space is maintained between the inner and outer gloves to provide additional protection against vesicants.

5. A glove for protection against chemical warfare agents such as mustard gas comprising an inner liner formed of light flexible fabric treated with a mustard gas` resistant material, and an outer glove of wear-resisting material, said liner and outer glove being attached only at widely spaced extremities thereof to thereby provide an air space between the main portions.
